Application filed ay 2'7, 1905. Serial No. 262.668-

.Madison and State of Indiana, have invented certain new and usefulImprovements in Electric Generators, of which the following is aspecification. g

The object of our invention is to produce a compact electric-generatorstructure in which the field may be advanced or retracted with relationto the armature in order to retard or advance the current-wave.

The accompanying drawings illustrate our invention as applied to amagneto-generator.

Figure 1 is an axial section; Fig. 2, a sectional View on line 2 2 ofFig. 1, and Fig. 3 a perspective detail of the shifting poles.

In the drawings, indicates a suitable base, to which are secured thestationary poles 11 11 and magnets 12, the poles 11 being shown asconnected by an intermediate nonmagnetic arch 13 for a purpose whichwill appear. Mounted between the poles 11 are two annular segmentalshifting poles 15, which at their ends are connected by nonmagneticsegments 14. The non-magnetic segments 14 and adjacent ends of theshifting poles 15 are threaded in order to receive journal-bearings 16.Attached to one of the bearings 16 is a shifting lever 17, and to theother bearing is attached a collector 18. J ournaled in one of thebearings 16 isashaft 19, to which a driving element 19 is attached, andjournaled in the other bearing 16 is a shaft 20. These two shafts areattaohed'to the opposite ends of the armature 21, which is mountedwithin the annular poles 15 to either rotate or oscillate. In thedrawings We show an alternating-current generator, and hence the shaft20 is hollow and is connected to the grounded side of the armature-winding, while a terminal 22 passes through the hollow shaft 20 and isconnected to the other side of the armature-winding in the usualwell-known manner. By this construction the shifting poles 15 15 may beshifted angularlywithin the stationary poles '11, so as to advance orretract the field with relation to the armature 21.

We are aware that it is common to advance or retract the field withrelation to the armature by swinging the entire structurec'. a, themagnets and polepieces-angularly with relation to the armature; but suchconstruction is expensive and undesirable. It is to be understood thatthe generator may be of any desired type without departing from ourinvention.

We claim as our invention In an electric generator, the combination,with stationary poles, of a pair of annular segmental poles journaledwithin said stationary poles and provided at the ends withjournalbearings, an armature mounted Within said annular poles andhaving shaft-sections journaled and supported in the journal-bearings ofthe annular poles, means by which the armature may be angularly movedwithin the annular poles, and means by which the annular poles may beshifted within the stationary poles.

In witness whereof we have hereunto set our hands and seals, atAnderson, Indiana, this 24th day of May, A. D. 1905.
